Heamodialysis Patients; Central Vein Stenosis Following Temporary Double Lumen Catherization In Internal Jugular And Subclavian Veins.
Professional Med J Jan ;24(8):1211-5.

Background: Internal jugular vein is considered the preferred site of insertion. Prevalence of central vein stenosis following temporary double lumen catheterization at different sites seems to be different in Asian countries. Objectives: To evaluate the number of cases having catheterization and stenosis after being subjected to central vein catheterization (CVC) among Pakistani population. Study Design: Cross sectional study. Period: 6 months period. Setting: Admitted in the Department of Nephrology or already undergoing maintenance hemodialysis fulfilling the inclusion criteria were included in the study. Material and Method: The sample which was considered suitable for this study was 150 cases after checking the inclusion criteria carefully. The patients were advised to undergo color Doppler ultrasonography of IJV and SCV of both sides. Demographics and outcome variables were noted and recorded for the analysis purposes. Data was analyzed used SPSS 20.inc Results: The frequency of catheterization of catherization at IJV was found to be 128(85.3%) and frequency of catheterization at SCV was 22(14.7%). The frequency of CVS at IJV was found to be 43(29.68%) and the frequency of CVS at SCV was 81(54.54%). The frequency of stenosis at SCV was found to be significantly higher with a p value of 0.029 (<0.05). Conclusion: Internal jugular vein is the most frequent and preferred site of temporary double lumen catheterization for haemodialysis as it is associated with significantly lower rate of stenosis as compared to subclavian vein.
